Same-day AC & heating service across Orange County — book online today
Inspection, repair, sealing, replacement and new installation, so your HVAC system delivers quiet, even airflow to every room.
At a glance
Your system is only as good as its ducts.
Leaky, undersized or poorly insulated ductwork wastes energy, creates hot and cold rooms and strains your system. We design, repair, replace and install home ductwork.
Duct inspection, leak detection and airflow testing
Sealing with mastic or UL-listed metal tape
Replacement and right-sizing of supply and return runs
New ductwork for remodels and room additions
Signs Your Ducts Need Attention
Hot or cold spots, weak airflow, or rooms that never feel right
Dusty home, musty odors, or visible debris around registers
High bills or long run times without better comfort
Loud ducts: whistling, rattling or popping
Visibly kinked, crushed or disconnected flexible ducts
Old tape peeling, missing insulation or rusted plenums
Ductwork Services We Provide
Duct Inspection and Testing
Camera inspections to spot kinks, disconnections, debris or moisture issues
Static pressure and airflow checks to confirm sizing and balance
Leak detection at boots, seams, plenums and equipment connections
Return-air evaluation to eliminate negative pressure and temperature swings
Duct Repair and Sealing
Seal joints and seams with mastic or UL-listed metal tape (never cloth duct tape)
Reconnect and mechanically fasten loose takeoffs and boots
Replace crushed or excessively long flex runs and correct sagging
Insulate ducts in attics, garages and crawlspaces to reduce heat gain and loss
Duct Replacement and Right-Sizing
When ducts are too small, too long or too leaky, replacement pays off. We re-design supply and return runs for balanced airflow, use rigid metal where appropriate and short, straight runs of quality flex only where it makes sense, properly support and seal all transitions, and commission the system for airflow, static pressure and room balance.
New Ductwork Installation
Residential ductwork installation for remodels, room additions and conversions
Zone-friendly layouts and provisions for filtration and indoor air quality upgrades
Clean, sealed installs that are serviceable and quiet
Maintenance and Duct Cleaning
Duct cleaning is done only as needed after inspection, for example after construction dust, vermin or verified mold. We scope cleaning properly and seal access points when work is complete.
Why Proper Design Beats Patchwork Fixes
Rules of thumb and random upsizing do not work. We follow load-based design and air distribution best practices so every register gets the airflow it needs: quieter operation, even temperatures, lower static pressure and a system that delivers its rated efficiency.
What Affects Ductwork Cost?
Home size, number of runs and access (attic, crawlspace, garage)
Scope: targeted sealing vs. full replacement
Materials: rigid metal, lined plenums, quality flex, insulation level
Extras: new returns, filtration cabinet, IAQ components
We provide written, itemized estimates with repair and replace options. Larger projects can be financed.
Ductwork FAQ
Do I need duct cleaning every year?
No. We inspect first and clean only as needed, such as visible debris, post-construction dust, pests or confirmed mold, then fix root causes and close access points.
What is better, rigid metal or flex?
We use rigid metal for trunks and plenums and short, properly supported flex for final runs. Design, length, tension and airtight sealing are the keys.
Can you add more return air?
Yes. Additional or larger returns often improve airflow, reduce noise and balance temperatures.
Will new ducts really save energy?
Properly sized, sealed and insulated ducts reduce losses and static pressure, helping equipment perform better. Pair duct work with AC or heating service for the best results.
